Luna's not in a rush to get married, but a mare does like feeling wanted, you know? So who cares if her first date in centuries is with some forgettable wannabe background pony? At least it will result in a night out of the castle, some much-needed romantic attention, and get her 'back in the game,' so to speak. And that's better than yet another night in, right?
It's a good thing that Celestia knows what's best for her little sister.

Rated "Teen" for allusions to the horizontal mambo. Nothing explicit, but better safe than sorry, right?
